VCC
Enable input for Driver 1. Pull low to disable Driver 1 (OUT1 will be low,
PWM1 will be ignored). Even though internally pulled up to VCC with a typ.
100kΩ resistor, it is recommended to pull high up to VCC to enable the
section. The pin features TTL/CMOS compatible thresholds.
PWM input signal for driver 1 featuring TTL/CMOS compatible threshold
and hysteresis.
It is internally pulled down to GND with a 10 μA current generator.
All internal references, logic and drivers are referenced to this pin. Connect
to the PCB ground plane.
PWM input signal for driver 2 featuring TTL/CMOS compatible threshold
and hysteresis.
It is internally pulled down to GND with a 10 μA current generator.
Driver2 output. The output stage is capable of providing up to 4A drive
current to the gate of a power MOSFET. IGBT are supported as well.
A small series resistor can be useful to reduce dissipated power.
